Phalangium is a genus of harvestmen that occur mostly in the Old World. The best known species is Phalangium opilio , which is so common in many temperate regions that it is simply called "harvestman".
Phalangium opilio is a univoltine species in Europe, producing one generation per year that overwinters as eggs. Two or more generations may occur within a year in some areas of North America, in which case eggs, immatures, and adults may all overwinter. [6]
Aug 4, 2021 · We assembled the first harvestman draft genome for the species Phalangium opilio, which bears elongate, prehensile appendages, made possible by numerous distal articles called tarsomeres. Here, we show that the genome of P. opilio exhibits a single Hox cluster and no evidence of WGD.

Phalangium is a genus of harvestmen found in Europe and western Asia, with the species P. opilio also found in North America and introduced to Australasia. A number of the species listed below are nomina dubia dating to early circumscriptions of this genus including a much broader range of species; most are probably not correctly placed.
Although P. opilio by itself appears unable to keep populations of any pest under control, it serves as one member of a complex of generalist predators that exist in many crops and that together are able to help keep pest densities low.

Genes encoding a putative farnesoic acid O-methyltransferase, called ‘FAMeT’, have been found in Malacostraca and Branchiopoda [19–21]. In addition, a gene homologous to the juvenile hormone acid O-methyltransferase (JHAMT), which converts FA to MF in insects [22], has been found in Daphnia[20].
